So I read Ian Chengs Emmisary's Guide to Worlding and this technique of using Johnstone-style "masks" to embody different aspects of the worldbuilding process strikes me as similar to some ideas in this "psychonaut field manual" my brother sent me awhile ago: https://orig00.deviantart.net/dca9/f/2018/094/8/e/the_psychonaut_field_manual_fourth_pdf_edition_by_bluefluke-d8rjuxc.pdf (yes it's a deviantart link 😅). It's sortof like a spiritually agnostic guide to occult/"magick" techniques.
